Performance Friction Direct Drive V3 Rotors Finally Released!

[HP Autosport]

Description

The Performance Friction 357.062.63 & 357.062.64 V3 Disc Rotor is a direct 2-piece rotor replacement for the BMW E9x M3 front brakes. They are designed to be used with the factory caliper, with no other parts or modifications necessary. Kit includes everything needed (rotor, hat and hardware) for a single rotor replacement. Priced per rotor.

The V3 design features an all new retention ring that holds the hat and disc together without the need for traditional nuts & bolts. The simplified design also helps save weight and makes rotor replacement a breeze. The 2-turn retaining ring is held in a groove in the hat that overlaps the rotor flanges, effectively locking the rotor to the hat.

2-piece rotors offer better cooling over a one-piece design. Performance Friction's full floating Direct Drive attachment system allows the brake disc to naturally expand/contract both radially and axially without being constrained by the hub. This helps eliminate rotor warping, vibrations and pulsations. Due to the high quality of Performance Friction's design and manufacturing, the Direct Drive rotors are completely silent and rattle-free - a trait not typically found in many competitor's 2-piece designs. The hat assembly is completely reusable - no need to buy the entire rotor again! And, because the rotor is designed for use with the factory caliper, you can still use your favorite Performance Friction brake pads!

Note: Performance Friction Brake Pads are recommended for this set up. All other pads must be checked for proper rotor clearance at installation and periodically as they wear. Some brands of brake pads will fit at time of installation, but may contact the rotor-hat during use which can lead to brake failure.
Technical Information

• V3 style mounting hardware
• High Carbon Alloy with copper and molybdenum for high temperature strength and durability.
• Vanes turned OD and ID for balance to reduce thermal warping and vibration.
• Runout less than .001 inches, reducing Pulsation and Vibration.
• Thickness variation less than .0003 inches reduces Pulsation and Vibration.
• 47 or more vanes for superior thermal capacity.
• Aircraft quality heat treated for micro structure alignment and durability.
• Surface finish less than .7 microns.
• 100% measured and inspected to meet tolerance specifications.

It doesn't need bolts to hold it in?

That makes me feel really uneasy.

[pbonsalb]

Think of it as having one giant nut?

Everything is locked in...It's like a huge snap ring that holds it all together. It's a revolutionary way to holding the hat and rotor ring together. Simple and quick DIY when it comes time for rotor ring replacement.

What is pricing relative to OEM?

Front and rears available?

[Datka]

Have these rotors with new rings been tested on the track?
If this is reliable for track abuse, then I am in.

[roastbeef]

will these be available for non-m cars?

[admranger]

I'm sure the rings will be track worthy. The version 1's I have on my E46M3 are the best rotors I've ever had in 21 years of doing track events.

Whether or not the new connection system proves to be a long term reliable product. It's innovative, and I like that. How it holds up long term is the question mark.

Not likely, but doesn't hurt to call PFC to inquire.

I am sure they have done extensive testing on the track as that is the main intend use of these rotors.

Rotor dimples are out of favor now (previous generation of PF)?

All are slotted now

Rear fitment?

[Richbot]

Almost all of the benefits listed in your OP already are sold by PFC as benefits of the V2 rotors

http://www.pfc.parts/aftermarket/direct-drive-discs/



So what I want to know is:

A) how much lighter than equivalent V2 rotors
B) how much less expensive to replace a friction ring
C) have they sold or licensed it to anybody for OE use yet

No, I don't recall PFC ever mad rear DD rotors for BMW applications.

Those are excellent questions. Will try to get answers for you.

My wild guesses are:

1 - lighter
2 - no stress point from the drilled hole in the head and rotor so stronger
3 - ease of installation/changing of rotor
4 - no user error on tightening torque sequence, etc on the bolts when changing rotor.



Also interested in rear application but major bummer they don't have one.

[Richbot]

It just seems like a really OE-friendly design. removing a dozen or more potential fastener failures from some brake system engineer's assembly process when he's putting a new system together for the 2019 Mullet GTSR-SpecV Type R Edition might make his life easier

I'm also curious if PFC ever plans to make a replacement rotor for the Stoptech kits. They have one for AP and Brembo in most of the popular setups. But I wouldn't be entirely surprised if they can't get in the ballpark with Centric on price

[HP Autosport]

PFC says the V3 rotors weigh about 1 lb. less compared to the same size V2 rotor assemblies. V3 assemblies are $38 less so replacement ring is less as well.

The V3 is used as OE on all of the Porsche builds for the Cayman GT4CS and GT3R. They are also on the BMW 235 Cup cars, which is the same as their E9x BBK, and it is the only kit they have in V3 at the moment. PFC's new Indy car package is also V3.

Has PFC provided you with V3 DD replacement rings to carry in stock for the E9X M3? When I was looking around in November, I saw the V2 replacement rings for the E9X for sale on multiple websites, but I couldn't find any E9X V3 rings on any websites.

No, nothing on the replacement V3 rotor ring yet. I will get an answer on that along with compatibility to the V2 hats.

Giggity, that's awesome and good for them for being responsive
